ok looking for so help. i just got done installing new convertor, new trans, new tune, and lt headers. everything is bolted back up and i was getting ready to crank it over to get the trans fluid to cycle, and i got nothing. the starter doesnt even crank it just does nothing. fuel pump turns on, and everything else but the starter doent seem to be turning on. i got under the truck and pulled the starter off everything is connected right, and the battery is fully charged. any ideas as to what could be happening?

im going to go back and double check all the connectors that i reinstalled.

 

check the fuse on the starter (underhood fuse center). was everything moving good when tightening the converter bolts?

 

Does the starter have power with the key in the "Start" position? (Purple wire)

Check the Ing C fuse should be a 20 AMP, also there is a ING A fuse 40 AMP that feeds the starter relay.

Does the starter have battery power? Red 10 Gauge wire wich has a a fuseable link.

 

This happened to me at the shop, it was the transmission safety switch wiring wasnt plugged in correctly, it wouldnot let power go to the stater as if I was trying to start it in gear.

 

figured it out. it was the small wire that connects to the starter, there is 2 studs on the starter and i had it on the wrong one. after that it fired right up.

thanks for the help
